  • Operating Voltage (Fingerprint Scan): 3.6V - 5Vdc
  • Operating Current: < 120mA
  • Interface: UART (TTL)
  • Fingerprint Scanning Time: < 0.5s
  • Average Searching Time: < 1s
  • Baud Rate: 9600bps
  • Resolution: 500dpi
  • Fingerprint Storage: 200
  • Scanning Area Dimension: 18.5 x 14.6mm
  • Outer Dimension: 47.7 x 20.5 x 21.2mm
  • Security Level: 1 to 5 (Default: 3)
  • False Accept Rate (FAR): <0.001% (security level 3)
  • False Reject Rate (FRR): <1.0% (security level 3)
  • Easy to use and Cost Effective

Working of Fingerprint Module

Each person’s fingerprint has a unique combination of ridges and valleys.

 

  • The sensor contains a light source and an image sensor which interprets the ridge as an ‘off’ and the valley as an ‘on’ (or it could be the other way around; the point is ridges and valleys are binary data).
  • This process creates an image of the fingerprint which is then digitally encoded.
  • The fingerprint sensor has its flash memory where it stores the data.
  • This data, called template, is 512 bytes; the sensor’s memory can store up to 127 / 200 templates.
  • For the sensor to recognize a fingerprint, it must store templates first to compare.
  • Hence, first-time users always need to run first an “enroll” program.
